Plans for the prevention of natural hazards were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor the development of urban planning and land use in areas at risk.
For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk.
Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones:
1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction;
2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue;
3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code).

1995年2月2日颁布的《加强环境保护法案》确立了自然灾害防治规划体系，该体系是国家开展风险防治工作的核心工具，其目标是对风险区域内的城市规划与土地利用发展情况进行监测。针对自然PPRs，《环境法典》第L562-1条划定了两类管控区域：一类为风险暴露区，另一类为未直接面临风险但可通过采取措施避免风险加剧的区域。根据灾害风险等级的不同，各区域均需执行强制性建设管控要求。现行法规通常将管控区域划分为三类：1. "禁止建设区"（又称"红色区域"）：此类区域灾害风险等级较高，基本原则为禁止一切建设活动；2. "限制建设区"（又称"蓝色区域"）：此类区域灾害风险等级中等，建设项目需符合适配问题类型的专项管控要求；3. 未直接面临风险，但建设工程、开发项目或农场、农业、林业、手工业、商业及工业活动可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。
